MOLD-INSERT-FEEDING MECHANISM.

Specification of Letters Patent.

Patented Sept. 20, 1921.

Application filed December 29, 1920. Serial No. 433,767.

T 0 all whom it may concern.

Be it known that I, Louis C. MARTIN, citizen of the United States, residing at Willoughby, in the county of Lake and State of Ohio, have invented certain new and use ful Improvements in Mold-Insert-Feeding Mechanism, of which the following is a specification.

'My invention relates to improvements in mold insert feeding mechanism adapted to carry and to feed in proper relative position within a mold cavity such inserts as it is desired to cast within the molded casting.

The present embodiment of this invention is particularly designed and adapted for use in supplying the small washer inserts upon the supporting studs of the mold cavities in the drag section of a flask preparatory to casting the ordinary rubber heels of com merce.

The primary object of the invention is to provide a generally improved insert holding and feeding mechanism adapted to carry a plurality of superposed inserts in proper relative positions with respect to the mold cavr' ties and to automatically and simultaneously deposit the lowermost washer or insert upon the pins or studs in the respective heel or mold cavity.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawing, and particularly pointed out in the appended claims.

Referring to the drawings, forming. a part of this specification, Figure 1 is a top plan view of a drag section of a flask provided with the usual heel forming cavities and in; sert supporting studs.

Fig. 2, a side elevation of the same equipped with a device for feeding and depositing the mold washer inserts upon the supporting studs, the insert feeding and guiding members being unequipped with the inserts for the purpose of illustration.

Fig. 3, a top plan view of the same.

Fig. 4, a sectional view of the drag section, with a partial sectional view of the mechanism taken on line 4.4' of Fig. 3, the feeding, guiding and. supporting members being equipped with washer inserts.

Fig. 5, a fragmentary sectional view of the same, the insert depositing and separating elements being in released. position pre paratory to rengaging the superposed insert above the lowermost ones after the deposlt of the latter on the shouldered portions of the insert supporting pins or studs in the heel cavity.

Fig. 6, a cross or transverse sectional view illustrating a modified form of insert feeding and guiding members together with a modifled form of insert depositing and separating elements.

Fig. 7, a top plan View of the same.

Fig. 8, a sectional view taken on line 83 of Fig. 6.

Fig. 9 is a view of a washer.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The drag section 1, of the flask may be of any suitable and convenient form, and so likewise as to the mold cavities 1*, and the inserts together with the means for supporting the latter in the mold cavity.

For the purpose of illustration and as showing one of the-various applications of my invention, I have shown my device applied to the drag section of a heel molding and vulcanizing flask, and hence the mold cavities P, are in the specific form of heel forming and vulcanizing cavities provided with the usual washer insert supporting studs 1". It will be seen that the studs 1 are provided with supporting shoulders and with reduced stem or pin portion 1.

Referring now to the improved insert holding and feeding mechanism to which this invention particularly relates, it will be seen that a suitable support or frame 2, is provided, said frame 2, in the present instance,

being provided with openings 2, to receive and contain the insert feeding, guiding and depositing mechanism hereinafter referred to.

As a means of properly positioning and adjusting the support 2, and the respective insert feeding and depositing devices with respect to the insert supporting studs 1, the support or frame 2, may be provided with adjusting legs or supports 3, having their lower ends adapted to fit into suitable openings l in the drag section of the flask.

As a means of providing suitable bearing supports for the various insert supporting, feeding and depositing mechanism, hereinafter described, the frame or support 2, may be provided with longitudinally, extending bars 4, pr VidBd With attachingscrews 4;,

and arranged, in the present instance, on opposite sides of the openings 2, in the frame 2.

As a means of properly holding, positioning and feeding a supply of inserts in the specific form of washer inserts 5, in proper relative position and immediately above the pin portions 1, of the supporting studs 1', suitable insert feeding and guiding members 6, are provided, said feeding and guiding members 6, being mounted, in the present instance, upon cross supporting members 7 In the form shown in Figs. 1 to 5, inclusive, of the drawings, the insert feeding and guiding members 6, are in the specific form of wire or guide members adapted to extend through the openings within the washer inserts 5, and are supported directly in the cross members 7, of the support 2, formed by the openings 2, while in the form shown in Figs. 6 to 8 of the drawings the insert feeding and guiding members 6, are in the specific form of tubes attached directly to the separate cross members 7, which also support the insert engaging, releasing and reengaging elements hereinafter referred to. 7

As a means of vertically su]i)porting the inserts 5, in their superposed relation on the feed and guide members 6, the cross supporting members 7 are provided with de pending movable elements 8, extending downwardly at the sides of the guide members 6, said elements 8, in the present in stance, being in the specific form of spring arms or tongues secured to the cross members 7 by means of the attaching elements or screws 8*. The lower or free ends of the elements 8, are provided with insert supporting and separating points or flan es 8*, said points 8", normally acting" to e1 ge at the side of the lowermost washer insert 5, in supporting the latter and the superposed inserts preparatory to dropping the column over the pin portions 1", of. the studs, as shown most clearly in Fig. l of the drawing.

As a means'of simultaneously moving or actuating the insert dropping and separating elements 8, the bearing bars a are provided with suitable openings adapted a; re ceive and contain a plurality of rock shafts the latter being provided at their ends with crank members 10, the free ends of the cranks" 10, being connected til a shitting bar 11 leading to an operating lever 12, the latter being connected to a bearing bracket 13, on the end of the support or frame 2.

In view of the tubular form of the feed ing andguitling members 6, shown in Figs. {are 8, inclusive, of the drawings and the fact that such guiding members 6, are mounted directly on the separate cross suppotting members-7*, which also support the insert depositing elements 8, the rock shafts are in the specific form of stub shafts 9, and the links or shifting bars 11, are connected to the cross bar 1%, carried by the operating lever 12.

In such tubular form of feed or guide elements 6, two oppositely arranged elements 8, are provided, the lower ends of the 'feeding and guiding tubular members 6, being provided with oppositely arranged notched recesses 6 to receive the points or flanges 8 which support the opposite edges of the lowermost washer insert before depositing, and for separating the latter from the superposed pile when the elements 8,;are 'eturned to their original positions by the return movement of the lever 12, and shif ing bars 11.

In the form shown in Figs. 6 to 8, in-

clusive, of the drawings, the stub shafts 9 are provided with oppositely disposed cam o 1 pin elements 9*, which wipe against thev base portions of the spring or movable elements 8, to reciprocate the latter in first depositing the lowermost washer insert, then returning and reengaging the washer. insert immediately above the one deposited on the shoulder portion of the stud 1 and then supporting the stack" or column of washer inserts until again brought into action for "epeating the automatic discharge of the next lowermost washer insert for loading up another series of heel forming cavities with such inserts. 7 Having thus described some of the em bodiments of my invention, without having attempted to set forth all the forms in which it may be made, or all the modes of its use, what I claim and desire to secure by Letters Patent, iS,
